New Guinea Impatiens plant named ‘Duerivdared’

ABSTRACT

A new and distinct cultivar of New Guinea  Impatiens  plant named ‘Duerivdared’, characterized by its upright, rounded and uniform plant habit; vigorous growth habit; dark green-colored leaves; freely branching and freely flowering habit; and red-colored flowers that are positioned above and beyond the leaves.

Botanical denomination: Impatiens hawkeri.

Cultivar designation: ‘Duerivdared’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of NewGuinea Impatiens plant, botanically known as Impatiens hawkeri, andhereinafter referred to by the name ‘Duerivdared’.

The new Impatiens is a product of a planned breeding program conductedby the Inventor in Rheinberg, Germany. The objective of the breedingprogram is to develop new freely branching New Guinea Impatienscultivars that flower early and have large flowers.

The new Impatiens originated from a cross-pollination made by theInventor in May, 2000 of a proprietary selection of Impatiens hawkeriidentified as code number S-016-219, not patented, as the female, orseed parent, with a proprietary selection of Impatiens hawkeriidentified as code number E-018-18, not patented, as the male, or pollenparent. The cultivar Duerivdared was discovered and selected by theInventor as a single flowering plant within the progeny of the statedcross-pollination in a controlled environment in Rheinberg, Germany inMay, 2003.

Asexual reproduction of the new cultivar by terminal cuttings inRheinberg, Germany since May, 2003, has shown that the unique featuresof this new Impatiens are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duerivdared’. These characteristics incombination distinguish ‘Duerivdared’ as a new and distinct Impatienscultivar:

-   -   1. Upright, rounded and uniform plant habit.    -   2. Vigorous growth habit.    -   3. Dark green-colored leaves.    -   4. Freely branching and freely flowering habit.    -   5. Red-colored flowers that are positioned above and beyond the        leaves.

Plants of the new Impatiens can be compared to plants of the femaleparent selection. In side-by-side comparisons conducted in Rheinberg,Germany, plants of the new Impatiens differed from plants of the femaleparent selection in the following characteristics:

-   -   1. Plants of the new Impatiens were more vigorous than plants of        the female parent selection.    -   2. Plants of the new Impatiens and the female parent selection        differed in flower color.

Plants of the new Impatiens can be compared to plants of the male parentselections. In side-by-side comparisons conducted in Rheinberg, Germany,plants of the new Impatiens differed from plants of the male parentselection in the following characteristics:

-   -   1. Plants of the new Impatiens were more compact than plants of        the male parent selection.    -   2. Plants of the new Impatiens and the male parent selection        differed in leaf and flower color.

Plants of the new Impatiens can also be compared to plants of thecultivar Fisnics Lired, disclosed in U.S. Plant Pat. No. 14,713. Inside-by-side comparisons conducted in Rheinberg, Germany, plants of thenew Impatiens differed from plants of the cultivar Fisnics Lired in thefollowing characeristics:

-   -   1. Plants of the new Impatiens had shorter internodes than        plants of the cultivar Fisnics Lired.    -   2. Plants of the new Impatiens had smaller leaves than plants of        the cultivar Fisnics Lired.    -   3. Plants of the new Impatiens had smaller flowers than plants        of the cultivar Fisnics Lired.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new cultivar, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ from the color values cited in the detailedbotanical description which accurately describe the colors of the newImpatiens. The photograph comprises a side perspective view of a typicalflowering plant of ‘Duerivdared’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Duerivdared has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensitywithout, however, any variance in genotype.

The aforementioned photograph and following observations andmeasurements describe plants grown in Rheinberg, Germany during thespring, under commercial practice in a glass-covered greenhouse. Plantswere about 16 weeks from cuttings and were grown in 12-cm containers.During the production of the plants, day and night temperatures averaged18° C. and light levels were about 4,500 lux.
